The species of this genus are among the smallest of the 

 family, and inhabit the West Indies and South America. The 

 fore-wings are narrower than the hind-wings, and twice as long ; 

 they are usually streaked with white or yellowish, and there is 

 a conspicuous white patch on the outer side of the hind margin 

 of the hind- wings. The antennae are long, and ciliated in the 

 males, and the abdomen is as long as the hind-wings.

All the wings are dark brown. The fore-wings have the 

 hind margins and the hinder angle slightly rounded, with a 

 series of more or less distinct creamy white spots extending 

 longitudinally from the base to the middle of the wings. The 

 hind-wings have a large patch of pure white covering the apex 

 and half the hind margin, including the fringes.
